KISSIMMEE, Fla. — Roger Clemens tried to get across a sense of urgency to Houston Astros pitchers Wednesday.

"If it's working for you, stay with it. If it's not, you need to change something. That's something I said," Clemens said. "Obviously it's not working for some of you so you need to re-evaluate what you're doing."

In his capacity as special assistant to the general manager, Clemens addressed a group of young pitchers who were often overmatched last season.
